Sonos "Adjust level" when grouped

[amegn1000]

When using the action "Adjust level" with grouped Sonos for a single speaker, the volume will be adjusted by the piston for all the speakers.
The initial trigger increases the volume or decreases the volume a lot more than the expected value for all the speakers, then the next triggers will increase / decrease the volume with the correct value but for all the grouped speakers.

Please see below.

Let me know...

Could it be an issue with the Sonos integration? It appears only one adjustment is made. Another problem that may occur is if the current level value in ST does not really match the Sonos speaker's level. Can you try adjusting the Sonos from its physical buttons and confirm that the level changes in ST?
